==Malformations== | |||
Come in three flavours: | |||
#Congenital pulmonary airway malformation (CPAM). | |||
#Extralobar sequestration (ELS). | |||
#Intralobar sequestrations (ILS). | |||
===CPAM=== | |||
General: | |||
*Classified according to density:<ref>Klatt. AOP. P.100.</ref> | |||
**Type I = mostly large cysts. | |||
**Type II = mostly small cysts. | |||
**Type III = solid mass. | |||
====Microscopic==== | |||
Features:<ref>Klatt. AOP. P.100.</ref> | |||
*Irregular cystic spaces with bronchial epithelium. | |||
**Bronchial epithelium = cilia, pseudostratified. | |||
===ELS=== | |||
General: | |||
*Typically not connected to airway tree/trachea. | |||
*Blood supply arises from aorta, ''not'' the pulmonary artery. | |||
*Mass lesion. | |||
*''Intralobular sequestration'' can be considered a variant of ELS; it is like an ELS but surrounded by normal lung. | |||
====Microscopic==== | |||
Features:<ref>Klatt. AOP P.100.</ref> | |||
*Abnormal airways: dilated bronchi. | |||
*+/-Infection. | |||
